Britney Spears takes on the role of Madonna in her ‘Glee’ cameo appearance.
The singer recently filmed her cameo for the TV musical drama and has posted a picture on her twitter page which shows her posing as the 52-year-old singer from their 2003 music video to their duet ‘Me Against The Music’.
In the picture Britney is wearing a white trouser suit, which is similar to what Madonna wore, while Heather Morris – who plays Glee member Brittany – takes on Britney’s role.
To accompany the picture, she wrote: "All my Gleekers in the crowd, grab a partner take it down - Brit."
As well as a cameo role, the special episode will also feature several songs from her back catalogue.
Show creator Ryan Murphy recently revealed the episode - entitled 'Britney/Brittany' - will poke fun at 'Glee' leader Mr. Schuester's reluctance to cover the pop star's music.
He said: "The entire episode is Mr. Shue saying, 'I don't want to do Britney.' We're doing it in a really fun, hallucinogenic way."
The Britney episode comes after 'Glee' writers previously penned special scripts dedicated to Madonna and Lady Gaga.
Ryan had previously spoken about his desire to get Britney on the show, saying: "Her people want to do it. Like Madonna, they gave me carte blanche. They know that we're fans of hers, and we're doing it in a very reverential way."
